Web Science/Part2: Emerging Web Properties/How big is the World Wide Web/An unrealistic, simplistic generative model/quiz

{Why is formulating a hypothesis so crucial in the process of scientific modelling?} + Formulating a hypothesis clears the path towards a clear defined model + Often simplifying assumptions are knit into the hypothesis and the afterwards built model

{Every Minute 0.19305 words are generated on the simple english wikipedia} - true + False
 * on average this number is true but this does not mean that every minute 0.19305 words are produced. Read more carefully next time!

{Why should one have several runs of a generative probabilistic model?} - in the first run the caches need to warm up + to get statistic stability + because random experiments can produce strong outliers in just one run - there is no cost of making sure the computer did correct calculations by running the experiment twice or more + because every scientific experiment should be repeated more than once to avoid mistakes
